What Is an Adjuster Bolt?
An adjuster bolt features a bowl-shaped base and is utilized for leveling, tilting, or adjusting the height of various equipment. By placing the base on the ground and screwing the bolt into the equipment legs, adjustments can be made easily. Available in standard and specialized types, including slip-resistant rubber bases, anti-vibration materials, and models suitable for inclined surfaces or earthquake-prone areas.
Uses of Adjuster Bolts
These bolts are essential for the stable horizontal placement of office and measuring equipment, machinery, and appliances on uneven surfaces. They facilitate height adjustments for kitchen equipment and can secure furniture to the ceiling to prevent tipping during earthquakes. Selection of the correct bolt size for the equipment’s weight is crucial.
Principle of Adjuster Bolts
The height adjustment of an adjuster bolt is achieved through rotation, with the adjustment degree dependent on the screw’s pitch and rotation angle. The rotation torque is influenced by the thread’s friction coefficient and the vertical load.
Types of Adjuster Bolts
Adjuster bolts cater to heavy-duty, anchor fixing, and sloping applications:
- For Heavy Load: Designed for higher load capacity, used for machinery, control panels, and vending machines, and available in saucer and wide-base types for greater floor adhesion.
- For Anchor Fixing: Features a base hole for anchor fixing, securing equipment firmly against vibrations.
- For Sloping: Allows angle adjustment for installation on sloped surfaces, unlike standard bolts which require level ground.
How to Select Adjuster Bolts
Selection involves considering the number of bolts for convenience, bolt size, and material based on load requirements. Base selection should account for floor conditions, while material and surface treatment choices depend on the environment and expected lifespan. For precise adjustments, fine-threaded bolts are recommended. Consideration of seismic measures and replacement for wear is also advised.
Structure of Adjuster Bolts
Made from steel, alloy steel, or stainless steel, with various surface treatments available to prevent rust. Bases come in anti-vibration, floor protection, and non-slip variants. Adjuster bolts are standardized for size, material, and treatment, though many market options exist.
